Comment:
The SG-1A was designed and built in 1970 as an
inexpensive, easy-to-build ship with gentle
flight characteristics. No special jigs or tools
are required other than a welding rig and common
hand tools. The boom-and pod design, which has
been static load tested to 9g without failure,
features a strut-braced aluminum wing with upper-
surface spoilers, a fixed wheel and a nose skid.
While the protype had constant chord, V-strutted
wings; the A version has double-tapered wings
with single struts.
